Hello, and I apologize in advance for asking too many questions.
A little backstory:
My mother is a US Citizen and she filed I-130 for my sister in March 2012. At that time my sister was married and was under the F3 category. In May of 2022, she and her children came to the U.S. under UHP parole due to war in Ukraine. Last year my sister's pending divorce was finalized and her category was changed to F1. In December 2023 she received the "Expedite Notification" that the U.S. Embassy in Frankfurt, Germany, approved the request to process my sister's immigrant visa case expeditiously.
We were advised that my sister can apply for AOS since they are lawfully present in the United States.
Questions:
I also need to make sure I understand the "Checklist of Required Evidence for form I-485" on the USCIS website. At first, they say this:
Family Members: If you are the spouse or child of a U.S. citizen’s immediate relative, you must independently qualify for adjustment of status and file your own application. You cannot qualify for adjustment of status as the derivative beneficiary based on the immediate relative’s application.
and later below
A copy of the Form I-797, Approval or Receipt Notice, for the principal applicant’s Form I-130 (unless you are filing your Form I-485 together with the principal applicant’s Form I-485);
1. Do we fill out 3 forms and submit them together? And we can include one check for all three?
2. When completing each form separately, what do we provide under the household income for the girls if neither works? My sister has a job now on a valid EAD.
3. I am a joint sponsor, so I am assuming I have to include three copies of the Affidavit of Support?
4. One of my nieces will turn 21 in March. Should we be concerned that she will "age out" while waiting on the approvals?
Any suggestions are appreciated. Thank you!
